I guess I was spoiled by Ricks in my early days and most recently a Highway 1 P, so I never really understood what you guys were going through heavy basses. Today I stopped by a friends place to see his new Martin. He wanted to jam, so he handed me his Alembic. I literally almost fell over because I wasn't expecting the weight. It has to be at least twice as heavy as my P. After about 20 minutes of not digging the bass at all, I grabbed his '78 P, which was more homey, but still no walk in the park in terms of weight. Later on I was having dinner with the wife and she remarked that I kept rubbing my neck and shoulder. At first, I didn't realize why it was aching, but putting two and two together, I don't know how you could handle that weight on one shoulder for 3 sets.
